St. Simeon Metaphrastes (fl. X Century) was a civil servant who became a monk when he was old. Little is known about his life. When he was secretary of statae, he compiled the ten volumes of the Menologion at the request of Emperor Constantine VII Porphyrogenitus. Simeon collected the lives of the saints from oral tradition and written collections. He copied some lives as written and rewrote others. He arranged the lives in the order of the saints' feast days, and his work became so popular that many earlier hagiography has been lost. He also wrote a history of the world and a collection of the sayings of the church fathers. Simeon is sometimes identified as Simeon Logothelite.
